Abstract
This invention is directed to a floor sander comprising a frame on wheels, a chassis carried by the frame, and a motor-driven sanding head mounted on the chassis generally adjacent the front of the chassis for rotation about an axis extending in side-to-side direction with respect to the chassis. The chassis is mounted on a pivot shaft extending in side-to-side direction with respect to the frame so that the sanding head can be raised and lowered relative to a surface to be sanded. The pivot shaft has first and second bearing assemblies at its ends. A first side of the chassis is movable up and down relative to the first bearing assembly, and a second side of the chassis is secured against up and down movement relative to the second bearing assembly. A guide system is provided for controlling the up and down movement of the first side of the chassis relative to the first bearing assembly so that the movement is in a vertical direction. A leveling mechanism can be operated to effect vertical movement of the first side of the chassis relative to the first bearing assembly and with respect to the second side of the chassis thereby to adjust the attitude of the chassis to position the axis of rotation of the sanding head in a plane common with an axis of rotation of the wheels on the frame.
